STREET-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 581,196, dated April20, 1897. Application filed September 1, 1896. Serial No. 604,502. (Nomodel.)

To all whom it may concern.-

Be it known that I, IRA W. CONSELYEA, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Sweepers for Asphalt andSimilar Roads or Streets, of which the following is a specification.

My invention has relation to a sweeper for roads, streets, or the like,and particularly adapted for use upon asphalt or similar streets, and insuch connection it relates particularly to the construction and arrangement of such a sweeper.

The principal object of my invention is to provide a sweeper adapted tobe propelled or carried by a tricycle or similar vehicle and operated bythe mechanism propelling the vehicle.

My invention will be more fully understood from the followingdescription, taken in connection with the accompanying drawings, formingpart hereof, and in which Figure l is a side elevational view of asweeper embodying main features of my invention. Fig. 2is a top or planview of Fig. 1; and Figs. 3 and 4 are enlarged detail viewsillustrating, respectively, in side elevation and partial section thepropelling mechanism for the vehicle.

' Referring to the drawings, the frame of the vehicle consists of thefollowing essential parts, to wit: a front post a, the saddle post orpillar b, the upper brace 17, joining the pillar b with post a, theinclined braces 17 b connecting a crank-hanger d with the post a, and asubstantially rectangular frame 6, extending backward from thecrank-hanger and forming at its rear end the support or aXle for therear wheels. This rectangular frame e supports the saddle-pillar 5.Depending from the rectangular frame at the front thereof are two armsd, slotted, as at 61 and braced by the connecting-arms (F. The two arms01' form at their slotted ends bearings for the shaft f of a revolublebrush f, the slots d being formed upon an arc of a circle to form ameans of adjustment toward or away from the ground of the shaft f andbrush f. Suspended by brackets or arms 9 from the frame 6 and directlyto the rear of the brush f is a box or receptacle h, the end adjacent tothe brush being curved, as at h, to partially inclose the brush f and toform a shield-like protection for the front of the brush. The floor ofthe box it has a hinged scraper-like portion 7& extending under thelower portion of the brush f, as clearly shown at Fig. 1. The rear ofthe boX his provided with a door h through which the accumulated debrismay be removed.

The tricycle is propelled, preferably, by the mechanism illustrated inFigs. 1, 3, and 4. The crank-hanger d is traversed by a shaft m,rotating within the hanger upon ball-bearings m. To this shaft m issecured at either end a ratcheted disk m and secured to one ofthesedisks is the main driving-sprocket m The disks m are each rotated bymeans of the pawls m carried by a treadle-arm m which when depressed bythe rider throws the pawls m into engagement with the ratchet-disks mThe treadles m oscillate upon a sleeve or cap 72, which is secured atone end to the crank-hanger d and projects over the shaft m, asillustrated in Fig. 4. On the cap or sleeve 17. is placed a coiledspring 02", one end being secured to the cap or sleeve, while the otherend rests under or is secured, as at 11 to the treadle-arm. This spring01 serves to elevate the treadle m The driving-sprocket m is connectedby a chain 0 with a sprocket 0, secured to the axle of the rear wheelsof the vehicle. The sprocket o is in turn connected by a chain 0 with asprocket 0 secured to the end of the brushshaft f.

As illustrated in the drawings, the sweeper is shown as driven by onerider sitting in the saddle p, but it is obvious that if necessary morethan one person may operate the sweeper, in which case the saddle isduplicated, and for each additional rider two additional treadles andmechanism operated thereby should be used.

Having thus described the nature and objects of my invention, what Iclaim, and desire to secure by Letters Patent, is-

In a street-sweeper, a revoluble brush, a tricycle the frame whereofsupports said brush, a crank-hanger, a shaft rotating therein, a disksecured to said shaft, a ratchet carried by said disk, a treadle-arinadapted to oscillate upon the shaft, a pawl mechanism actuated by saidtreadle and adapted to engage the ratchet and thereby rotate said disk,a rear axle, a sprocket thereon, a driving-chain connecting the diskwith the sprocket, a shaft carrying the revoluble brush, a sprocketthereon and a chain adapted to drive the brush-shaft from the rear axle,substantially as described.
